Getting locked out of your home, your computer, or anywhere else you want to be can suck. The same goes for those times when your gadgets prevent you from doing what you want to do with them, but it doesn't have to be that way. Here are the top 10 ways you can break into virtually anything with a literal or figurative lock.

8. Break Into an Airplane Lavatory

You know, for emergency purposes. All you need to do is flip up the sign push the lever into the unlocked position. We verified this on a recent flight and the tip comes from our trustworthy friends over at Hipmunk, so watch your back next time you're peeing on a plane. Or, of course, get that door open if someone is having an emergency and stuck inside the bathroom.

7. Unlock Region-Free Encoding on Your DVD or Blu-ray Player

One of the more annoying aspects of DVD and Blu-ray players is the region encoding, forcing you to only play discs made for you part of the world. Want to import a movie from another country? You're probably out of luck. Fortunately VideoHelp.com has DVD/Blu-ray player unlocking database so you can perform the necessary operation and watch whatever you want from wherever it came from.

6. Eliminate PDF Passwords

It's pretty annoying when you find a PDF or get one in your mailbox and it's locked down by a password. If you want to get rid of that password, Amit Agarwal has a Pdfs Pdfss guide to opening PDFs regardless of their protection. You can also check out Free PDF Unlocker (Windows-only) if you only need to enable copy and paste functionality. Just be sure to only use these options if you lose a password or you have a good reason to break in.

5. Unlock Your Camera's True Capabilities

If you've got a Canon point-and-shoot, you can install custom firmware CHDK to unlock a ton of features Canon didn't offer with your model. If you've got a Canon or Panasonic DSLR or micro-4/3rds camera, Magic Lantern can do the same (although it's video-oriented). If you wish your camera was a little bit better or you can't afford an upgrade right now, these hacks are great and providing you with features you probably should've had in the first place.

3. Pick Locks and Crack Safes

Learning to pick locks (regular ones or on your car) and crack safes may seem likes a thieve's trade, but knowing how to do it can provide you with a few legal benefits. First of all, you'll have a better understanding of how locks work so you can survey your own and protect yourself against their vulnerabilities. Additionally, should you lock yourself out, you'll know how to get back in.

2. Crack Passwords

Whether you're cracking a Wi-Fi password or learning how to break into a computer, cracking passwords can be useful. As with anything that falls more on the dark side, knowing these unsavory tactics can help you protect yourself. But when it comes to Wi-Fi, sometimes you just need to borrow a network temporarily and that's really harmful to anyone. Also, you might forget your own password and need to break back into your computer. Whatever the case may be, use these skills for good!
